CAR-ROOF.

Applieation filed January 29, 1919.

T0 all whom it may erinnern.'

lie it known that il, lavan l. Monenr, a` citizen of the United States.residing at Chicago, count)Y of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Car-Roofs, of which theJfollowing is a,deseription.

In the drawing:

Fig. P5 is an enlarged detail sectional view on the line 3 2 Vig. L.

Fig. 4 is an enlarged detail sectional View showing the flexible jointbetween roof sheet and the eaves flashing.

Fig. is a detailed plan view of a` car roof illustrating anotherembodiment of' my invention,

The object of my invention is to provide, for securing the roofsheets inoperative position on the ear and free to more about to a limitedextent.

The invention consists in positioning the roof sheets and holding themdown upon the roof' Vsubstrluture b v means at the marginal edges of theroot' sheets and leare the sheets free to move about within certainlimitations,

mount the roof sheets that they may move 'as if on a pivot at theirridge ends.

A further ohject'of' my invention is to proride a construction at theridge whereby the roof sheets may7 pivot on their ridge corners.

Further objects and particulars of the invention will appear from thefollowing description of the roof construction shown in theiweoinpanying drawings.

The reference numeral 1 designates a suitable roof sheathing of a car. i

The roof plates or sheets 2 are connected at their eaves end to a`fiashing 3, the 'joint between the fiashing and the roof sheets being aloose fiexilole joint as shown, in detail in Fig. 4.

The side marginaledges of the roof sheets are provided with upwardly1standing rebent flanges 4 which interlock with-a seam cap 5. Between themarginal flanges t of the roof' sheets I position a mullion 6 which issuitably secured to the roof sheathing, threbeing a space between theside niarginal flanges 4 and the mullion whereby the Specification ofLetters Patent.

sheets are free to more with respect `to said mullion.

The ridge end of the roof plate or sheet is provided with an openre-bend (it which overlies the upper face of the roof' plate and isadapted to receive a filled strip 7 which is suitably secured thereinand extends approximately the width of the sheet or plate. As will beseen from the d awing the wood filler or strip extends beyond the freeedge of' the bend (L the object of which will be hereinafter stated.

A ridge cap S is provided with down wardly extending side 'flanges 9which terminate at the bottom in an outwuirdlr extending flange lllwhich flange l() overlies the roof' sheet or plate 2. It will be seenthat the ridge, ends of the root' plates. on opposite sides oi' theridge` are normall;v spaeed from each other under the ridge cap` whilewood filler strip 7. carried b v the roof plates is in contact with theside flanges 9 of' the ridge capv The wood filler strip T extends bevondthe free edge of the bend (i of the plate 2 so that the edge of the bend6 is prevented from eenling into contact with the side flanges El of theridge cap, thereblveliminating the possibilities of said edge cuttingthrough the ridge cap. This is ot importance bei-anse the roof sheets orplates are prevented from moving bodilyY toward the eaves of the car b vreason of the filler strip T abutting the side flange ofthe ridge cap`besides which the roof sheets or plates.I being free at its marginaledges to more to compensate for service movement of the ear, withoutinjuriY to the. Sheets or plates`r and in such movements said platesfrequently pivot on its ridge corners said corners being fulcrumed onthe side ianges of the ridge cap and as the wood fillenstrip 7 contactswith the flange of the ridge cap.` there is no danger of the ridge capbecoming worn or eut b v such pivotal action of the root plate.

Therunning hoard saddle l1 has a recess 12 of a size to receive theridge cap as shown 4in Fig. 1. the side walls of the recessapproximately fitting against the outer face of the side flanges 9 ofthe ridge Cap. wherel the said side flanges are sustainedy againststress in a direction toward the eaves of the car. A

All joints between the parts at the eaves, roofs seams, and ridge areweather proof.

The wood filler strip 7 constitutes a rigidifyng element acrossthe ridgeend of the roof sheet or plate which stitfens and` reinforces the ridgeend' and prevents the ridge end of the plate from buckling or beingdistorted by stresses incident to the .service movements of the car androof so that there is very little, if any, likelihood of the roof platebecoming jammed at the ridge, therefore the joint between the ridge apand the rootI plate is always maintained normal, whereby the slippingaction at said joint is always free.

In Fig. 5 the construction is substantially like that heretoforedescribed, the only exception being that the filler strip 7a is convexon its eaves edge whereby the roof plates rocks on said convex edgeinstead of pivoting on its corners as described in connection in Figs.1, 2, and 4. In this construction it will be seen that there is arunning hoard saddle l1 positioned opposite the apex of the convex edgeof the liller strip T.

From the above it will be seen that in the construction shown in Figs.l, 2 and 4, the roof plates are movably mounted on the substructure andspaced apart at the ridge and at the side marginal edges, and have afree loose flexible connection with the flashing at the eaves, and Iarefree to pivot at their ridge corners to compensate for service movement;while in Fig. o the Construction is the same with the exception that thefiller strip is convex .on its eaves side, whereby the sheet or roofplates pivot at a point between their side marginal edges at their ridgeends.

The abutment of the filler strip on the ridge end of the sheet or platesis the sole means of restraining bodily movement of the roof platestoward the eaves of the car.
